CAR-TRUCK To all'whom it may coment:

Be 1t known that I, HARRY C'. STIGKEL, a

' citizen of the United States, residing at Star i `and usefulCar-Truck, of which the followv' Junction, in the county of Fayette andState of Pennsylvania, have invented a new ing is a specification.

The invention relates to improvements in car trucks.

Heretofore when the springs of a. car

truck become weakened and permit the bol- -ster to sink and cause thecar coupling to drop below its normal position and interfere.

withfthe proper coupling of the cars, it has been the practice tointerpose a board between the springs and thebolster for elevating thelatter..

The object of the ,present invention is to lmprovethe construction ofcar trucks, and to provide'a simple, strong and efficient car truck ofcomparatively inexpensive construction, equipped with means for enablingthe springs and the bolster to be readily adjusted in a verticaldirection to hold the same at the proper elevation to maint-ain the carcoupling at the standard height.`

Fig. 2 is a plan view of a portionof thesame.y Fig. 3 is a vertical sectional view on the line 3 3 of Fig. 2.Fig. 4 is a similar view on the line 4 4 of Fig. 2. Fig. 5 is 'avertical sectional -view on the line 5-5 of Fig. 2. Fig. 6 is a.

horizontal sectional view on the line 6-6 of Fig. 1. Fig. 7 is a detailsectional view on the line 7-7 of Fig. 1. Fig. 8 is a detail perspectiveview of thespring piank. Fig. 9'is a detail perspective view of thebolster retaining plate.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

In the accompanying drawings in which is illustrated the preferredembodiment of the invention, 1 designates a side frame, constructed ofcast metal, or other suitable material and provided with a centralbolster receiving opening 2 and having vertical colum'nguides 3 at,'opposite sldes of the opening. The truck bolster 4 is interlocked withthe column guides by means of oppo Specification of Iletters Patent.

bolster. The bolster .may be -of any preferred construction, and thecentral opening 2 of the side frame 1 is enlarged at the top at oppositesides at 6, the extensions or enlargements 6 -of the openingbeinglocated above' the column guides, and adapted to permit the bolster tobe introduced into the opening 2' and slidably engaged with the columnguides 3. The bolster is retainedin its interlocked relation with thecolumn guides by means of the top plate 7, fitted 1n and conforming tothe configuration of the enlarged top portion of the opening 2 andprovided at its outer face with a marginal flange 8, extending along thetop and around the ends of the bolster confiningplate vand fitted in acorresponding recess 9 of the side frame, as clearly shown in Fig. 6 ofthe drawings, whereby the-bolster confining plate .is arranged in-.flushrelation with the side frame, The bolster confining plate is alsoprovided with spaced transverse ribs 10, fitting in transverse grooves11 in the top wall of the opening 2 and. projecting from the inner faceof the side frame and provided with registering perforations 12 for thereception of a key 13, or other suitable fastening device, wherevby'th'e bolster confining plate is detachably locked in the enlarged topportion of the opening 2. By this construction, the bolster is securelyconfined in its interlocked relation with the side frames of the truck.

The bolster is supported b v coiled springs 14, which may be of anypreferred construction. The springs 14, which are preferably arranged inpairs, are seated .upon the end of a spring plank 15, provided withupwardly extending longitudinal side flangesv 16 and seated upon anadjustable bottom plate 17. The -bottom plate, which is adapted to beadjusted by screws 18, is provided at its ends with recesses 19,receiving the guide columns 3, whereby the bottom plate is slidablyinterlocked with the same. The screws 18, which are mounted in threadedopenings 20 in the bottom wall or sill 21 of the opening 2, have reducedupper portions 22, which extend into registering openings 23 and 24 ofthe spring plank and the adjustable plate. The screws present supportingshoulders' 25 to the ad:

other suitable lool, whereby the scri-ws nur. be adjusted, should Ilbecome nwessary to raise the .sprlngs and the bolster lo maintain Thisadjustment will obviate the inconwnience of interposng a board betweenthe bolster and the springs, which has heretofore been necessarjv toraise the bolster and the car coupling to the proper height.

The side frames are provided at their ends with upper and lowerhorizontal arms 27 and QS to receive standard journal boxes 29, whichare secured in place by bolts 30. ller plates 3l of either wood ormetalbeing preferably interposed between the lower arms 28 and the journalboxes 29. The filler plates are adapted to be removed so as to affordsuthcient space between the arms to permit the journal boxes to bereadily removed and replaced. The bolts 30 pierce the filler plates andretain the same in place.

The side frames are provided at their inner faces with hollow integralstuds 32, located at opposite sides of. the opening 2 at the top thereofand forming seats for pins from which the vertical beams are :suspended.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is:-
